摘要
车辆牌照自动识别系统在桥梁、路口自动收费、停车场无人管理、违章车辆自动记录等领域有着广泛的应用.研究重点是系统中的牌照字符分割技术,在介绍了LLT快速分割算法之后对其进行了改进,并将其应用于牌照图像的字符快速分割,准确率得到了明显的提高.
Vehicle license plate recognition system plays an important role in intelligent traffic control,parking lot monitor and vehicle charging system.The technology of character extraction is researched in this paper.After introducing LLT segmentation,it brings forward a improved method and gets a satisfied effect.
